July 23 (Reuters) – Belgian-Dutch immunology company argenx said on Thursday global sales of its lead drug Vyvgart jumped in the second quarter of 2026 from a year earlier.
Vyvgart sales came in at $1.516 billion in the second quarter, up 60% from $949 million a year earlier, as the company continued to expand autoimmune treatment in generalised myasthenia gravis (gMG) and chronic inflammatory demyelinating polyneuropathy (CIDP).
During the quarter, the company expanded Vyvgart’s label in the United States to cover all gMG serotypes.
After scaling the brand in gMG and CIDP, argenx is seeking to deepen penetration through additional administration options and potential label expansions.
It is also looking to prove it can become more than a one-franchise biotech through pipeline assets such as empasiprubart and other earlier-stage immunology programmes.
Argenx said results from all scheduled studies remain on track to be released as planned.
